Principle: This Electromagnetic Induction Demonstrator experiment demonstrator is designed to visually prove the existence of a field around a current-carrying conductor, making it an essential educational supply for physics education.Visual Demonstration: The apparatus clearly shows the deflection of a compass pointer when an electric current moves through the overhead wire, providing a direct and intuitive demonstration of Electromagnetic Induction Demonstrator's Law.User-Friendly Design: Featuring a stable base, clear markings, an built power switch, and secure binding posts for easy connection, this physics experiment apparatus is built for and straightforward classroom use.Construction: Built with a sturdy metal base and quality components, this electromagnetism demonstrator is designed to withstand repeated use in a busy classroom or science environment.Engaging Learning Tool: By allowing students to observe the effect of electric current firsthand, this current field demonstrator transforms abstract concepts into a tangible and memorable hands-on experience.","image_url":"https://cdn.shopify.com/s/files/1/0807/5486/8463/files/67c11029-23d3-46f2-bea7-57987f84cfed.jpg?v=1786020350","href":"/product/wp-dcd-10001018912.html","buy_url":"https://uecyem-u1.myshopify.com/products/wp-dcd-10001018912","buy_url_source":"shops.shop_domain
